Xerographic cassette with dual waste toner storage
First Claim
1. A xerographic cassette for a printing machine and a copying machine comprising:
- an imaging surface, having an interior surface and an exterior surface opposed to one another;
a cleaning device for removing particles from said imaging surface;
means for conveying the particles removed from said imaging surface into the interior surface of the imaging surface, the interior surface of the imaging surface forming an interior imaging storage container for holding the particles collected therein; and
an auxiliary waste toner storage container being positioned adjacent to said interior imaging storage container, said conveying means passes through said auxiliary waste toner storage container, said conveying means being adapted to release particles into said auxiliary waste toner storage container until said auxiliary waste toner storage container is substantially full, whereafter the particles of said auxiliary waste toner storage container being conveyed into said interior imaging storage container, and said auxiliary waste toner storage container defining an aperture therein enabling emptying of said auxiliary waste toner storage container.

Abstract
A xerographic cassette for a printing or copying machine includes a photoreceptor drum, a cleaning blade, and a waste toner conveyor for conveying waste toner cleaned off the photoreceptor drum by the cleaning blade into the interior of the photoreceptor drum for storage. The conveyor includes a flexible helical wire which acts as an auger. A curved tube portion of the conveyor passes through an auxiliary waste toner container. Once the auxiliary container is substantially full, waste toner is conveyed into the interior of the photoreceptor drum. The auxiliary container is provided with an aperture which enables it to be emptied, thereby prolonging the useful life of the cassette.
